IMPROVEMENT IN MACHINES FOR ST RETCHlNG AND FCLDING MOSQUITO-NETTING.

Specification'forming part of Letters Patent No. 39,868, dated September-8. lSl3.

To all whom it may concern:

Be it known thEIt'JACOB A. VAN RIPER, of

Spring Valley, in the county of Rocltla-nd and State of NewYork, and LEWIS VA RIPER', deceased, who was of the same place, county and State aforesaid, did invent a new and Improved Machine for Stretching and Folding Mosquito-Netting and Similar Fabrics; and be it further known that I, JACOB A. VAN RIDER,

sponding parts in the several figures.

This invention consists in the employment or use of aseries of oblique rollers, arranged in pairs and used in connection with feeders and a reciprocating bed, all arranged as hereinaft'er shown and described, whereby the work of stretching and folding the nettingor other material maybe done in an expeditious and perfect manner.

To enable those skilled in the art to fully understand and donstruct the invention, I willproceed to describe it.

A represents a framing, which may be const noted in any proper manner to support the working parts ofthe device; and B represents a series of pairs of rollers, which are placed at each side of the framing on its topand in an oblique position, as shown clearly in Fig. 1. The pairs of rollers at each side of the framing A are parallel with each other. These rollers are rotated from shafts O O by means of gears 01,, the shafts O C being rotated from a driving-shaft,-D, and theshaft (3 of ear-h. pairs ofrollers being connected by gears b.

.The bearings of the rollers B are attached to plates E, which are adjustable in a transverse direction with the framing, in order that the rollers may be adjusted to suit the width of the fabric F to be stretched.

G represents aseries of rollers, which are placed transversely in the framing A, and are connected at one end by gears a, and are driven 'from the shaft D through the medium ofgears'd, (Shownin Fi al.) Oncoftherollers (ah-the smallest one, has its shaft 0 provided with gearsf at its ends, one of whichnieshes into a gear, S, on oneend of a shaft, II, the

opposite end of said shafthaving a.- crankpulley, 11-, upon it, which is connected by a pitman, I, with an arm, 13, on a shaft, J. This shaft J has two cross-heads, jj,-upon it, which have each a spring, is, attached to each end, and to the lowerendsofthese springs or feeders plates K are attached, said plates or feeders being between rollers L L, the shafts l of which have pinions m on them, which gear into racks M M, whichjjwork on guides n attached one to each sideof the framing.- The racks M M are counected'by two parallel bars,

-N N, in which two shafts, 0 0', are placed transversely, a shaft beingneareach rack llI, as shown in Fig. l. The shafts 0 0 have ropes or straps 2 passing around them, to the lower ends of which weights 0 are attached, and a platform, P, is attached to the shafts o o by ropes q. The two shafts 0 0 are connected by a rope,'r, to insure a uniform movement of the two shafts 0 0. The weights 0 have a tendency to keep the platform elevated. l lach rack M has a pendent'plate, Q, attached to it, and from one of these plates a pin, .9, projects horizontally and fits into an oblongslot, t, in theupper end of a lever, R, which has its fulcrum at it. This lever B is connected by a pitrnan, Gnwith the gear 9 of the shaft H.

'lhe'gearf at the end of the shafte of the roller G--the gear not hitherto describedmeshes into a wheel, mat the lower end of an inclined shaft, T, the upper end of which has a wheel, 10, upouit, which gears into a wheel, a, on a roller, U, which is directly'over the shaftJ.

V is a small roller which. rests upon the roller, U. I

The operation is as follows: The fabric 1* passes between, feed-rollers \V'W, and the edges-0t the fabric pass between the oblique rollers B. The fabric then passes around the rollers G and the roller U, and down between the plates K K and upon the platform 1?, as shown'clearly in Fig. 2. The fabric. F is stretched transversely by the rollers 13' and down on the platform.- The rollers L L serve as guides for the plates K K and the'fabr'ic.

The reciprocating movement of. the platform P is produced by the lever R, pit'madG and gear 9 at the end of the. shaft H. The rollers L L are rotated in consequence of the pinions' 7n gearing into the racks M M.- -'.l.his'f0lding v of'the fabricF, of course, measures it, as 'the folds are of annii'orm lengthf' The platform P,in consequence of bein g snspen'd'ed,a-s shown, with weights connected with it, is-allowed to Having thus described theinvention, what is claimed as new} and for which. Letters Patcm is desired, is-

1. The reciprocating platforrn P, in-onnec-I 'tionwith the reciprocating plates or feeders KK and rollers L 'L, all arranged substantially- Ias and for the purpose set forth.

- '2. The combination of the-oblique rollers B, l platform iP, plates -K-, and rollers G, all ar.-" ranged for joint operation, as andforthe pup pose specified.
